The bong water is the heart of water filtration. How much you fill it and how often you change it significantly impacts taste and draw quality. Fresh water is one of the easiest ways to a better session.
How much water should go in the bong?
The rule of thumb: enough so that the bottom end of the downstem is one to two centimeters submerged in the water. Too little water filters poorly; too much splashes into the mouthpiece when drawing. For bongs with a percolator, the additional chamber must also be covered.
How often should you change bong water?
Ideally after every session. Old water is the biggest taste killer: it collects residues, becomes cloudy, and quickly smells unpleasant. If you want the best taste, empty the bong after smoking and rinse it briefly.
How do I recognize bad bong water?
- Cloudiness – clear water becomes milky or brownish.
- Odor – stale water quickly smells foul.
- Film – a layer on the water's surface.
Tips for bong water
Some swear by cold water or ice cubes for a cooler draw. More important than such tricks, however, is regularity: fresh water and a clean bong. How to keep your bong thoroughly clean can be found under Bong Cleaning.
